o all whom it may concern:

Be it known that I, HENRY G. VOIGI-IT, a citizen of the United States,residing at New Britain, county of Hartford, State of Connecticut, haveinvented certain new and useful Improvements in Overhead Sash-Pulleys,of which the following is a full, clear, and exact description.

This invention relates to improvements in overhead sash pulleys, and themain object is to provide an improved construction which is so adaptedto a window casing that it may readily be applied thereto after thecasing has been set up, the same furnishing a neat and finishedappearance when in place.

In the drawings Figure 1 is a side elevation of the device as it appearsin place. Fig. 2 is an end elevation of the parts shown in Fig. 1looking from right to left. Fig. 3 is a View similar to Fig. 1, thepulley being shown as partly inserted in the act of assembling. Fig. 4is a plan view. Fig. 5 is a plan view of the upper corner of a windowcasing recessed, or mortised, in a manner suitable to receive thepulley.

1 represents the head jamb, or lintel, of a window casing; 2 representsthe side-stile, these parts meeting in the usual manner -to form a rightangle. The meeting ends of the lintel 1 and the side stile 2 arerecessed, or mortised, to form a passage at the corner through which thepulley is passed and in which said pulley stands when the parts areassembled ready for use. The major part of the mortise is preferablyformed in the lintel 1. The main passage formed by the mortise, ornotch, in the lintel 1 is indicated at 3 (Fig. 5). The mortise or notchin the side-stile is preferably provided with two side shoulders 4--4,which when present may constitute supporting ledges, the space betweensaid shoulders being to afford clearance for the pulley hereinafterdescribed. The rear end of the mortise in the top stile is preferablyundercut, as indicated at 5 (Fig. 3) to receive the tail end of theupper part of the pulley frame later described.

The construction of the pulley and its frame is substantially asfollows: 6 represents the pulley wheel of any suitable design, usuallyhaving a grooved peri hery. This pulley 6 is mounted on a pivot carriedby a frame 8. The frame 8 is provided with an exposed and finished undersurface 9. The two edges of the frame, indicated at 1011 respectively,are preferably substantially parallel and extend obliquely to the undersurface 9. 12 is a depending ex- Patented Dec. 5, 1911.

tension or arm constituting part of the frame and arranged at rightangles to the surface 9. The part 12, when in place, faces against theside-stile 2. The passage formed by the notches in the head-jamb andsidestile is of such size as to permit the pulley and its housing to bepassed through the same diagonally, as shown in Fig. 3, so that saidframe and pulley may be inserted from the exposed side of a window frameafter the latter has been set up. When the frame and pulley are finallyin place, as shown in Fig. 1, the angular exposed part of the frame willlie flush with the surfaces of the head-jamb and. side-stile. 14- is aholding screw by which the arm 12 may be secured to the side-stile 2. Ifdesired, another holding screw 15 may be passed through the otherexposed. end of the frame so as to take into the top lintel 1. The pivot7 for the pulley will, when the parts are assembled, stand above theside-stile 2 and preferably slightly outside of a center line passingtherethrough, so that any tendency of any weight suspended by the pulley6 would tend, if anything, to tilt the frame in a di rection to liftthat end located in the undercut recess 5, while the weight will becarried by the support afforded to the part 12 by the shoulder at thelower end of the recess in the side-stile in which said part 12 islocated. Indeed, when the ledges l-4 are provided, some of said weightmay be carried thereby, since the diagonal edge 11 of said frame mayrest thereon. The frame may be formed in any desired way,-for example,by a casting or by being built up of two or more parts. 16 is aclearance passage in the overhead wall, or surface, 9, through which asash cord may pass as it hangs down from the inner side of the pulley 6,said end of the sash cord being attached to the window sash (not shown)in the usual manner.

What I claim is:

In an overhead pulley construction, a frame including two exposed rightangular portions both arranged to overlap the exposed inside surfaces ofa Window casing at screw passage in each of said right angular cornerthereof, a pulley housing extending portions. diagonally upwardtherefrom, a pulley pivotally mounted in said diagonally ex- HENRYVOIGHT tending housing, said right angular por- Witnesses:
